WRONG! Newton's gravity is F = GMm/r^2. Notice how there is a single 
term on the right side? There is no "+" symbol to indicate where two 
forces are added, nor a "-" symbol where two forces are subtracted. ONE 
TERM, and definitely NOT a composite force.

Where do you show your theory as falsifiable? Where is your experimental 
evidence?

Oh good grief. You are getting wronger and wronger. The centrifugal 
(pseudo)force is OUTWARD, AWAY from the center. You yourself commented 
about being thrown off a merry-go-round by the centrifugal force.

Also if you use the centrifugal pseudoforce to explain how centrifuges 
work, they work because the centrifugal force forces the dense/heavy 
matter OUTWARD and the lighter/less dense matter gets displaced inward. 
NOT TANGENTIALLY.

> 2. The centripetal acceleration is caused by the attractive EM force derived from the earth and the moon are expanding in the same direction as the universe expands.

Gibberish nonsense. In the earth moon system the centripetal force and 
gravity are one and the same.
